From 28605a22f564860c885bde42ad91840e9aacec45 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 28 Mar 2019 08:11:21 +0100 Subject: Revert "audio: fix pc speaker init" This reverts commit bd56d378842c238c8901536c06c20a4a51ee9761. Turned out it isn't that simple as the device needs the pit object link. So "-device isa-pcspk" isn't going wo work anyway. We are in freeze, so just reverting the thing is the best way to handle this for now, trying to come up with something better can be done in the 4.1 devel cycle. Also add a comment noting the object link.

However the conversion code doesn't do anything to the string buffer if the passed in speedmask doesn't match any of the recognized speeds, which means that the tracing and error messages will end up with random garbage in them. This can happen if we're doing USB device passthrough. Handle the "unrecognized speed" case by using the string "unknown".

Also the audiodev timer-period property gets converted like a frequency. Only handling of the legacy QEMU_AUDIO_TIMER_PERIOD environment variable is correct because it's actually a frequency. With this patch the property timer-period is really a timer period and QEMU_AUDIO_TIMER_PERIOD remains a frequency. Fixes: 71830221fb "-audiodev command line option basic implementation."
